I'm a 24 year old 120lb female who works out moderately. Almost a year ago when on a short run, I started feeling this sharp pain in my right knee towards the lower, outside area. I used to run track for years and never had any knee issues. It started out of no where and ever since, if I go on a run for longer than .75 mile, I get the same sharp pain again. If I continue running with the pain, I'll feel it in the same spot for the next 24-48 hours, especially when going downstairs/upstairs and of course when running. I've stopped running for a long time in hopes this would solve the issue, but after going for a run again recently it came right back. I plan on seeing a doctor for it but I wanted to see if anyone could help me on here.
